Mostly Assembly (x86), C/C++, Visual Basic, QBasic, (GWBasic, but not anymore :lol: ), Assembly (SPARC).
Also some Java, Pascal, Python, PHP.
A few misc others that probably aren't really worth mentioning and have mostly been forgotten. (HTML, SQL, Haskell, Assembly (6502)).
Does COM IDL count? Not really programming but it is a computer language. Looks like it may come in handy for interfacing C++ to VB. (Still learning this one I guess).
